Question

What is this simplified?

Answer 1

If this expression didn't have variables but just numbers replacing them, you would give each piece a common denom. and then add. Do the same thing with the variables and then add them.

Answer 2

would the denom be x(x-1) ?

Answer 3

For example

\[\frac{1}{x+5}+\frac{10}{x^2+5x}\rightarrow\frac{1}{x+5}+\frac{10}{x(x+5)}\]
the common Denom. is x(x+5) so all we need to do is multiply the first term by (x/x)
\[\frac{1}{x+5}+\frac{10}{x(x+5)}\rightarrow\frac{1}{x+5}\frac{x}{x}+\frac{10}{x(x+5)}\]\]
\[\frac{x}{x(x+5)}+\frac{10}{x(x+5)}=\frac{5+10}{x(x+5)}=\frac{15}{x(x+5)}\]

Answer 4

yes!

Answer 5

be careful with the negative signs though:)

Answer 6

so would it x-1 or x+1 ?

Answer 7

\[x^2+x\rightarrow x(x+1)\]

Answer 8

is the answer 1-x/x(x+1) ?

Answer 9

yes!

Answer 10

Thanks!!!!!
